摘要
无线传感器网络具有实际应用环境相对复杂、自身节点通道脆弱等特点,因此传感器节点很容易受到虚假数据注入攻击,导致传感器能量和通信资源浪费,甚至造成系统瘫痪。途中过滤技术是解决以上问题的有效方法之一。文章首先介绍了途中过滤技术的基本原理;然后对途中过滤技术中密钥分配、事件报告生成、途中过滤和接收器验证4个步骤进行研究分析,并根据不同原则分别对密钥分配过程和途中过滤过程进行分类研究,详细分析了一些重要的过滤方法及其优缺点。
Because the actual environment of wireless sensor network application is relatively complex and the wireless network itself node channel is fragile,sensor nodes are vulnerable to false data injection attacks,resulting in waste of sensor energy and communication resources,and even system paralysis.En-route filtering technology on the way is one of the effective ways to solve the above problems.Firstly,this paper began with an introduction to the basic principles of en-route filtering technology.Secondly,specific technical research was carried out on the four steps of key distribution,event report generation,enroute filtering and sink verification in the en-route filtering technology.According to different principles,the key distribution process and the en-route filtering process were classified and studied,and some important filtering methods and their advantages and disadvantages were analyzed in detail.
